The existing ARINC429 bus communication equipment cannot satisfy the situation of multi-channel simultaneous detection on Integrated Display and Control System. To solve this problem, the design of ARINC429 bus communication equipment based on PCI interface was researched. Meantime, this paper emphasized the method of using C# to design Integrated Display and Control System Measurement Software. The overall structure was built up based on the idea of structuralization, modularization and standardization; in order to accomplish the connection between user application, PCI driver and interface control procedures of hardware, the interface function provided by communication board was called; Form from Visual Studio 2010 was adopted to realize visual operation interface. By comparing the sending and receiving data of the test software and the Integrated Display and Control System, we can quickly identify the problematic bus channel and implement the fault analysis and diagnosis of system. 
